Entering Drive Parameters
You can also enter the hard disk drive parameters. The drive parameters are:
Parameter
Description
Type
The number for a drive with certain identification parameters.
Size
The formatted capacity of the drive is the number of heads times the number of
cylinders times the number of sectors per track times 512 (bytes per sector).
Cyln
The number of cylinders in the disk drive.
Head
The number of heads
Wpcom
The actual physical size of a sector gets progressively smaller as the track
diameter diminishes. Yet each sector must still hold 512 bytes. Write
precompensation circuitry on the hard disk compensates for the physical
difference in sector size by boosting the write current for sectors on inner tracks.
This parameter is the track number on the disk surface where write
precompensation begins.
LBA Mode
Toggles Logical Block Addressing mode.
Block Mode
Toggles multi-sector transfer mode.
PIO Mode
Sets the transfer speed. The slowest speed is PIO mode 0; the fastest speed is PIO
mode 5, or Ultra DMA mode.
32 Bit Mode
Toggles 32 bit transfer mode.
Sectors
The number of sectors per cylinder. MFM drives have 17 sectors per track. RLL
drives have 34 sectors per track. SCSI and IDE drives have even more sectors
per track.
Boot Sector Virus Protection
This parameter toggles virus protection for the boot sector of the system drive. The Optimal
default setting is Disabled.
